4 Billionth dice bet is close 
If the rewarding bet doesn't fit the requirements, the next valid bet will be the winner.
Those are some good prizes!
Less than 11.6 million bets left until 4 billionth bet, and since around 3,000 bets per minute are made currently, it means that 4 billionth bet will be made within the next 64 hours. But of course the users' activity can intensify when we are closer to the event, so I won't be surprised if ti will happen tomorrow.
I have a question regarding the rewards distribution. If the very first valid bet will be, say 4,003,000,000, will it be rewarded with 0.02 BTC instead of 0.1 BCH, and will all the other rewards be shifted downwards?
